Further compounds of formula (A) may be prepared by reacting a compound of formula (Q) with a suitable triarylbismuth compound under conditions described, for example, by A. Yu. Fedorov et al., Russ. Chem. Bull. Int. Ed., (2005), Vol. 54, No. 11, 2602-2611, and by P. Koech and M. Krische, J. Am. Chem. Soc., (2004), Vol. 126, No. 17, 5350-5351 (2004) and references therein.

The compounds of Formula (I) according to the invention can be used as herbicides in unmodified form, as obtained in the synthesis, but they are generally formulated into herbicidal compositions in a variety of ways using formulation adjuvants, such as carriers, solvents and surface-active substances. The formulations can be in various physical forms, for example in the form of dusting powders, gels, wettable powders, water-dispersible granules, water-dispersible tablets, effervescent compressed tablets, emulsifiable concentrates, microemulsifiable concentrates, oil-in-water emulsions, oil flowables, aqueous dispersions, oily dispersions, suspoemulsions, capsule suspensions, emulsifiable granules, soluble liquids, water-soluble concentrates (with water or a water-miscible organic solvent as carrier), impregnated polymer films or in other forms known, for example, from the Manual on Development and Use of FAO Specifications for Plant Protection Products, 5th Edition, 1999. Such formulations can either be used directly or are diluted prior to use. Diluted formulations can be prepared, for example, with water, liquid fertilisers, micronutrients, biological organisms, oil or solvents.

The formulations can be prepared, for example, by mixing the active ingredient with formulation adjuvants in order to obtain compositions in the form of finely divided solids, granules, solutions, dispersions or emulsions. The active ingredients can also be formulated with other adjuvants, for example finely divided solids, mineral oils, vegetable oils, modified vegetable oils, organic solvents, water, surface-active substances or combinations thereof. The active ingredients can also be contained in very fine microcapsules consisting of a polymer. Microcapsules contain the active ingredients in a porous carrier. This enables the active ingredients to be released into their surroundings in controlled amounts (e.g. slow release). Microcapsules usually have a diameter of from 0.1 to 500 microns. They contain active ingredients in an amount of about from 25 to 95% by weight of the capsule weight. The active ingredients can be present in the form of a monolithic solid, in the form of fine particles in solid or liquid dispersion or in the form of a suitable solution. The encapsulating membranes comprise, for example, natural and synthetic gums, cellulose, styrene-butadiene copolymers, polyacrylonitrile, polyacrylate, polyester, polyamides, polyureas, polyurethane or chemically modified polymers and starch xanthates or other polymers that are known to the person skilled in the art in this connection. Alternatively it is possible for very fine microcapsules to be formed wherein the active ingredient is present in the form of finely divided particles in a solid matrix of a base substance, but in that case the microcapsule is not encapsulated.

The formulation adjuvants suitable for the preparation of the compositions according to the invention are known per se. As liquid carriers there may be used: water, toluene, xylene, petroleum ether, vegetable oils, acetone, methyl ethyl ketone, cyclohexanone, acid anhydrides, acetonitrile, acetophenone, amyl acetate, 2-butanone, butylenes carbonate, chlorobenzene, cyclohexane, cyclohexanol, alkyl esters of acetic acid, diacetone alcohol, 1,2-dichloropropane, diethanolamine, p-diethylbenzene, diethylene glycol, diethylene glycol abietate, diethylene glycol butyl ether, diethylene glycol ethyl ether, diethylene glycol methyl ether, N,N-dimethylformamide, dimethyl sulfoxide, 1,4-dioxane, dipropylene glycol, dipropylene glycol methyl ether, dipropylene glycol dibenzoate, diproxitol, alkylpyrrolidone, ethyl acetate, 2-ethyl hexanol, ethylene carbonate, 1,1,1-trichloroethane, 2-heptanone, alpha-pinene, d-limonene, ethyl lactate, ethylene glycol, ethylene glycol butyl ether, ethylene glycol methyl ether, gamma-butyrolactone, glycerol, glycerol acetate, glycerol diacetate, glycerol triacetate, hexadecane, hexylene glycol, isoamyl acetate, isobornyl acetate, isooctane, isophorone, isopropylbenzene, isopropyl myristate, lactic acid, laurylamine, mesityl oxide, methoxypropanol, methyl isoamyl ketone, methyl isobutyl ketone, methyl laurate, methyl octanoate, methyl oleate, methylene chloride, m-xylene, n-hexane, n-octylamine, octadecanoic acid, octylamine acetate, oleic acid, oleylamine, o-xylene, phenol, polyethylene glycol (PEG 400), propionic acid, propyl lactate, propylene carbonate, propylene glycol, propylene glycol methyl ether, p-xylene, toluene, triethyl phosphate, triethylene glycol, xylenesulfonic acid, paraffin, mineral oil, trichloroethylene, perchloroethylene, ethyl acetate, amyl acetate, butyl acetate, propylene glycol methyl ether, diethylene glycol methyl ether, methanol, ethanol, isopropanol, and higher molecular weight alcohols, such as amyl alcohol, tetrahydrofurfuryl alcohol, hexanol, octanol, ethylene glycol, propylene glycol, glycerol, N-methyl-2-pyrrolidone and the like. Water is generally the carrier of choice for the dilution of the concentrates. Suitable solid carriers are, for example, talc, titanium dioxide, pyrophyllite clay, silica, attapulgite clay, kieselguhr, limestone, calcium carbonate, bentonite, calcium montmorillonite, cottonseed husks, wheatmeal, soybean flour, pumice, wood flour, ground walnut shells, lignin and similar materials, as described, for example, in CFR 180.1001. (c) & (d).

A large number of surface-active substances can advantageously be used both in solid and in liquid formulations, especially in those formulations which can be diluted with a carrier prior to use. Surface-active substances may be anionic, cationic, non-ionic or polymeric and they may be used as emulsifiying, wetting or suspending agents or for other purposes. Typical surface-active substances include, for example, salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; salts of alkylarylsulfonates, such as calcium dodecylbenzenesulfonate; alkylphenol-alkylene oxide addition products, such as nonylphenol ethoxylate; alcohol-alkylene oxide addition products, such as tridecyl alcohol ethoxylate; soaps, such as sodium stearate; salts of alkylnaphthalenesulfonates, such as sodium dibutylnaphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2-ethylhexyl)sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryl trimethylammonium chloride, polyethylene glycol esters of fatty acids, such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; and salts of mono- and di-alkyl phosphate esters; and also further substances described e.g. in “McCutcheon's Detergents and Emulsifiers Annual”, MC Publishing Corp., Ridgewood, N.J., 1981.

Further adjuvants which can usually be used in pesticidal formulations include crystallisation inhibitors, viscosity-modifying substances, suspending agents, dyes, anti-oxidants, foaming agents, light absorbers, mixing aids, anti-foams, complexing agents, neutralising or pH-modifying substances and buffers, corrosion-inhibitors, fragrances, wetting agents, absorption improvers, micronutrients, plasticisers, glidants, lubricants, dispersants, thickeners, anti-freezes, microbiocides, and also liquid and solid fertilisers.

The formulations may also comprise additional active substances, for example further herbicides, herbicide safeners, plant growth regulators, fungicides or insecticides.

The compositions according to the invention can additionally include an additive comprising an oil of vegetable or animal origin, a mineral oil, alkyl esters of such oils or mixtures of such oils and oil derivatives. The amount of oil additive used in the composition according to the invention is generally from 0.01 to 10%, based on the spray mixture. For example, the oil additive can be added to the spray tank in the desired concentration after the spray mixture has been prepared. Preferred oil additives comprise mineral oils or an oil of vegetable origin, for example rapeseed oil, olive oil or sunflower oil, emulsified vegetable oil, such as AMIGO® (Rhône-Poulenc Canada Inc.), alkyl esters of oils of vegetable origin, for example the methyl derivatives, or an oil of animal origin, such as fish oil or beef tallow. A preferred additive contains, for example, as active components essentially 80% by weight alkyl esters of fish oils and 15% by weight methylated rapeseed oil, and also 5% by weight of customary emulsifiers and pH modifiers. Especially preferred oil additives comprise alkyl esters of C₈-C₂₂ fatty acids, especially the methyl derivatives of C₁₂-C₁₈ fatty acids, for example the methyl esters of lauric acid, palmitic acid and oleic acid, being important. Those esters are known as methyl laurate (CAS-111-82-0), methyl palmitate (CAS-112-39-0) and methyl oleate (CAS-112-62-9). A preferred fatty acid methyl ester derivative is Emery® 2230 and 2231 (Cognis GmbH). Those and other oil derivatives are also known from the Compendium of Herbicide Adjuvants, 5th Edition, Southern Illinois University, 2000.

The application and action of the oil additives can be further improved by combining them with surface-active substances, such as non-ionic, anionic or cationic surfactants. Examples of suitable anionic, non-ionic and cationic surfactants are listed on pages 7 and 8 of WO 97/34485. Preferred surface-active substances are anionic surfactants of the dodecylbenzylsulfonate type, especially the calcium salts thereof, and also non-ionic surfactants of the fatty alcohol ethoxylate type. Special preference is given to ethoxylated C₁₂-C₂₂ fatty alcohols having a degree of ethoxylation of from 5 to 40. Examples of commercially available surfactants are the Genapol types (Clariant AG). Also preferred are silicone surfactants, especially polyalkyl-oxide-modified heptamethyltrisiloxanes, which are commercially available e.g. as Silwet L-77®, and also perfluorinated surfactants. The concentration of surface-active substances in relation to the total additive is generally from 1 to 30% by weight. Examples of oil additives that consist of mixtures of oils or mineral oils or derivatives thereof with surfactants are Edenor ME SU®, Turbocharge® (Syngenta AG, CH) and Actipron® (BP Oil UK Limited, GB).

The said surface-active substances may also be used in the formulations alone, that is to say without oil additives.

Furthermore, the addition of an organic solvent to the oil additive/surfactant mixture can contribute to a further enhancement of action. Suitable solvents are, for example, Solvesso® (ESSO) and Aromatic Solvent® (Exxon Corporation). The concentration of such solvents can be from 10 to 80% by weight of the total weight. Such oil additives, which may be in admixture with solvents, are described, for example, in U.S. Pat. No. 4,834,908. A commercially available oil additive disclosed therein is known by the name MERGE® (BASF Corporation). A further oil additive that is preferred according to the invention is SCORE® (Syngenta Crop Protection Canada.)

In addition to the oil additives listed above, in order to enhance the activity of the compositions according to the invention it is also possible for formulations of alkylpyrrolidones, (e.g. Agrimax®) to be added to the spray mixture. Formulations of synthetic lattices, such as, for example, polyacrylamide, polyvinyl compounds or poly-1-p-menthene (e.g. Bond®, Courier® or Emerald®) can also be used. Solutions that contain propionic acid, for example Eurogkem Pen-e-trate®, can also be mixed into the spray mixture as activity-enhancing agents.

The herbicidal formulations generally contain from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, of a compound of Formula (I) and from 1 to 99.9% by weight of a formulation adjuvant, which preferably includes from 0 to 25% by weight of a surface-active substance. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations.

The rate of application of the compounds of Formula (I) may vary within wide limits and depends upon the nature of the soil, the method of application (pre- or post-emergence; seed dressing; application to the seed furrow; no tillage application etc.), the crop plant, the weed or grass to be controlled, the prevailing climatic conditions, and other factors governed by the method of application, the time of application and the target crop. The compounds of formula I according to the invention are generally applied at a rate of 1 to 4000 g/ha, especially from 5 to 1000 g/ha. Preferred formulations have especially the following compositions:

(%=percent by weight):

Emulsifiable concentrates: active ingredient: 1 to 95%, preferably 60 to 90% surface-active agent: 1 to 30%, preferably 5 to 20% liquid carrier: 1 to 80%, preferably 1 to 35% Dusts: active ingredient: 0.1 to 10%, preferably 0.1 to 5% solid carrier: 99.9 to 90%, preferably 99.9 to 99% Suspension concentrates: active ingredient: 5 to 75%, preferably 10 to 50% water: 94 to 24%, preferably 88 to 30% surface-active agent: 1 to 40%, preferably 2 to 30% Wettable powders: active ingredient: 0.5 to 90%, preferably 1 to 80% surface-active agent: 0.5 to 20%, preferably 1 to 15% solid carrier: 5 to 95%, preferably 15 to 90% Granules: active ingredient: 0.1 to 30%, preferably 0.1 to 15% solid carrier: 99.5 to 70%, preferably 97 to 85%

The invention relates also to a method for the selective control of grasses and weeds in crops of useful plants, which comprises treating the useful plants or the area under cultivation or the locus thereof with a compound of Formula (I).

Crops of useful plants in which the compositions according to the invention can be used include especially cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and for non-selective weed control. The term “crops” is to be understood as also including crops that have been rendered tolerant to herbicides or classes of herbicides (for example ALS, GS, EPSPS, PPO, ACCase and HPPD inhibitors) as a result of conventional methods of breeding or genetic engineering. An example of a crop that has been rendered tolerant e.g. to imidazolinones, such as imazamox, by conventional methods of breeding is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®. The weeds to be controlled may be both monocotyledonous and dicotyledonous weeds, such as, for example, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.

Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt-176 maize hybrids of NK® (Syngenta Seeds). The Bt toxin is a protein that is formed naturally by Bacillus thuringiensis soil bacteria. Examples of toxins and transgenic plants able to synthesise such toxins are described in EP-A-451 878, EP-A-374 753, WO 93/07278, WO 95/34656, WO 03/052073 and EP-A-427 529. Examples of transgenic plants that contain one or more genes which code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®. Plant crops and their seed material can be resistant to herbicides and at the same time also to insect feeding (“stacked” transgenic events). Seed can, for example, have the ability to express an insecticidally active Cry3 protein and at the same time be glyphosate-tolerant. The term “crops” is to be understood as also including crops obtained as a result of conventional methods of breeding or genetic engineering which contain so-called output traits (e.g. improved flavour, storage stability, nutritional content).

Areas under cultivation are to be understood as including land where the crop plants are already growing as well as land intended for the cultivation of those crop plants.

EXAMPLE 1 Preparation of 2-(2,6-diethyl-4-methylphenyl)-5-[2-(ethylthio)propyl]cyclohexane-1,3-dione (Compound number T7 in Table T1)

Step 1

Ethanethiol (1.48 ml, 20.0 mmol) is added dropwise to a mixture of 1.66 ml crotonaldehyde (1.66 ml, 20.0 mmol) and 0.02 ml triethylamine (0.02 ml, 0.1 mmol) and the mixture is stirred at room temperature for 4 hours, then concentrated under reduced pressure to give 3-(ethylthio)butyraldehyde (2.66 g) as a yellow liquid which is used without further purification in the next step.

Step 2

1-Triphenylphosphoranylidene-2-propanone (12.77 g, 40.0 mmol) is added to a solution of 3-(ethylthio)butyraldehyde (5.30 g, 40.0 mmol) in dichloromethane (100 ml) and the mixture is heated under reflux for 24 hours. The reaction mixture is cooled to room temperature, and the solvent evaporated in vacuo to give a beige solid. The crude product is taken up in a 1:1 mixture of hexane:ether (the insoluble material is discarded), and then concentrated under reduced pressure to give an orange oil which is further purified by column chromatography on silica gel to give 6-(ethylthio)hept-3-en-2-one as a yellow oil.

Step 3

Hexane washed sodium (0.73 g, 32.0 mmol) is added to ethanol (40 ml), stirred at 0° C. under nitrogen. After 2 hours of stirring, a solution of diethyl malonate (4.64 g, 29.0 mmol) in ethanol (20 ml) is added dropwise over 5 minutes, and once the addition is complete, the cooling bath is removed and reaction mixture is allowed to warm to room temperature. The reaction mixture is stirred at room temperature for 1 hour, then cooled again to 0° C.

A solution of 6-(ethylthio)hept-3-en-2-one (4.2 g, 24.0 mmol) in ethanol (20 ml) is added dropwise over 10 minutes. Once addition is complete, the cooling bath is removed and reaction mixture is allowed to warm to room temperature. The reaction mixture is stirred for 24 hours at room temperature, then poured into 2M aqueous hydrochloric acid (200 ml). The reaction mixture extracted with dichloromethane, and the combined organic extracts are dried over anhydrous magnesium sulfate, filtered, and the filtrate evaporated in vacuo to give a yellow gum, which is dissolved in a mixture of 2M aqueous sodium hydroxide solution (75 ml) and propan-2-ol (25 ml) and then stirred at room temperature for 44 hours. Some of the solvent (by roughly one quarter to one half) is removed under reduced pressure, and the reaction mixture is acidified carefully to pH 2 by the addition of concentrated hydrochloric acid. The reaction mixture is heated to 70° C., held at 70° C. for 30 minutes, and then the heat removed and reaction allowed to cool to room temperature. The reaction mixture is extracted with ethyl acetate, and the combined organic extracts are dried over anhydrous magnesium sulfate, filtered, and the filtrate is evaporated in vacuo to give a yellow gum. Further purification by column chromatography on silica gel affords 5-[(2-ethylthio)propyl)cyclo-hexane-1,3-dione as a yellow gum.

Step 4

A solution of 5-(2-ethylthio)propyl)cyclohexane-1,3-dione (2.50 g, 11.7 mmol) and sodium carbonate (1.24 g, 11.7 mmol) in a mixture of water (35 ml) and ethanol (5 ml) is prepared, and then add dropwise over 5 minutes to a mixture of (diacetoxyiodo)benzene (3.76 g, 11.7 mmol) and sodium carbonate (1.24 g, 11.7 mmol) in water (40 ml) at room temperature. The reaction mixture is stirred for 2 hours at room temperature, then extracted with dichloromethane. The organic extracts are combined, dried over anhydrous magnesium sulfate, filtered, and the filtrate is evaporated in vacuo to give the iodonium ylide, used without further purification in the next step.

Step 5

The iodonium ylide (1.90 g, 4.56 mmol), prepared in Step 4,2,6-diethyl-4-methyl-phenylboronic acid (1.05 g, 5.48 mmol), palladium (II) acetate (0.082 g, 0.36 mmol), lithium hydroxide monohydrate (0.766 g, 18.24 mmol) are stirred together a mixture of 1,2-dimethoxyethane (40 ml) and water (10 ml) under an atmosphere of nitrogen and then heated to 50° C. for 4.75 hours. The mixture is cooled to room temperature, filtered through celite, and the celite washed with 2M aqueous hydrochloric acid (80 ml) and 40 ml ethyl acetate (40 ml). The mixture is poured into a separating funnel, the organic layer is separated, and the aqueous layer is extracted with ethyl acetate. The organic extracts are combined, dried over anhydrous magnesium sulfate, filtered, and the filtrate is evaporated in vacuo to give a brown gum. Purification by column chromatography on silica gel gives 2-(2,6-diethyl-4-methylphenyl)-5-[2-(ethylthio)propyl]-cyclohexane-1,3-dione as a pale yellow gum.

EXAMPLE 2 Preparation of 9-(2,6-diethyl-4-methylphenyl)-3-oxaspiro[5.5]undecane-8,10-dione (Compound Number T22 in Table T1)

Step 1

To a solution at 5° C. of potassium hydroxide (12.85 g, 0.229 mol) in a mixture of water (50 ml) and ethanol (200 ml) is added dimethyl 2-oxopropylphosphonate (38.0 g, 0.229 mol), followed by the dropwise addition of tetrahydropyran-4-one (15 ml, 16.4 g, 0.163 mol). The clear solution is stirred for 5 hours at room temperature.

Most of the solvent is removed from the reaction mixture under reduced pressure, and the residue is diluted with tent-butyl methyl ether and water. The organic layer is separated, the aqueous layer is extracted twice with tert-butyl methyl-ether, the combined organic phases dried over anhydrous sodium sulfate, filtered and the filtrate concentrated in vacuo.

The crude product is purified by distillation under reduced pressure to give 18.8 g (82%) of product with a boiling point of 102-104° C./12 mbar. ¹H-NMR reveals the product to be a 4:1-mixture of the desired 1-(tetrahydropyran-4-ylidene)propan-2-one and an isomer, 1-(3,6-dihydro-2H-pyran-4-yl)propan-2-one which is used without further purification in the next step.

Step 2

To a solution at room temperature of the product of Step 1 (13.18 g, 94.0 mmol) in 100 ml of ethanol (100 ml) is added diethyl malonate (14.3 ml, 15.09 g; 94.2 mmol), followed by the dropwise addition of a ˜2.72 M solution of sodium ethoxide in ethanol (36.6 ML˜94.1 mmol). The solution is stirred for 3 hours at room temperature, then for 1 hour at reflux.

The solvent is removed from the reaction mixture under reduced pressure and the solid residue is taken up in 12N aqueous sodium hydroxide (150 ml) and stirred at room temperature over night. The alkaline aqueous mixture is washed once with tert-butylmethyl ether, then acidified to pH 2-3 using concentrated hydrochloric acid and warmed to 70° C. for 2 hours. The aqueous mixture is extracted with ethyl acetate and dichloromethane, and the organic phases are combined, dried over anhydrous sodium sulfate, filtered and the filtrate concentrated in vacuo. The solid residue is taken up in tert-butyl methyl ether, the mixture stirred, and the off-white solid collected by filtration to give 3-oxaspiro[5.5]undecane-8,10-dione (12.3 g), m.p. 162-164° C.

Step 3

3-Oxaspiro[5.5]undecane-8,10-dione (5.47 g, 30.0 mmol) is stirred in a mixture of water (50 ml) and ethanol (16 ml) at 0° C. and lithium hydroxide monohydrate (2.52 g, 60.0 mmol) is added. When the solution becomes clear, (diacetoxyiodo)benzene (9.65 g, 30.0 mmol) is added at once and the mixture is stirred for 45 min at 0° C., followed by 3 hours at room temperature.

The reaction mixture is diluted with 1,2-dimethoxyethane (200 ml) and 2,6-diethyl-4-methylphenylboronic acid (6.50 g, 33.8 mmol), palladium(II) acetate (0.5 g, 2.23 mmol), and lithium hydroxide monohydrate (5.05 g, 120.0 mmol) are added at 0° C. The mixture is warmed to 50° C. and as it thickens after ca. 1-2 hours, it is further diluted with a mixture of water and 1,2-dimethoxyethane (50+50 ml). After addition of a further catalytic amount of palladium(II) acetate, stirring at 50° C. is continued for about 16 hours.

The reaction mixture is diluted with ethyl acetate and water, and the alkaline water layer is extracted twice with ethyl acetate. The combined organic layer is discarded and the aqueous phase further diluted with ethyl acetate and acidified at 0° C. to pH 2-3 using 4N aqueous hydrochloric acid. The organic layer is separated, the water layer is extracted twice with ethyl acetate, the combined organic phases dried over anhydrous sodium sulfate, filtered and the filtrate concentrated in vacuo.

The crude product is purified by flash filtration first (ethyl acetate/hexane 3:1), followed by flash chromatography (ethyl acetate/hexane 3:2→2:1). The yellowish oil obtained after concentration is taken up in a 4:1 mixture of hexane:tert-butyl methyl-ether, the mixture stirred, and the white solid is collected by filtration to give 9-(2,6-diethyl-4-methylphenyl)-3-oxaspiro[5.5]undecane-8,10-dione, m.p. 139-141° C.

The organic extracts are combined, dried over anhydrous sodium sulfate, filtered and the filtrate concentrated in vacuo. The oily residue is taken up in hexane under stirring, and the white solid is collected by filtration to give 2,6-diethyl-4-methylphenylboronic acid. The filtrate is concentrated and purified by column chromatography on silica gel give a further quantity of desired product. A combined yield of 16.6 g (78%) of 2,6-diethyl-4-methylphenylboronic acid is obtained.
